Adobe Illustrator on iPad versions 3.0.7 and earlier are affected by an Integer Underflow (Wrap or Wraparound) vulnerability. This vulnerability allows arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction, as a victim must open a malicious file.
With a CVSS score of 7.8, this vulnerability is classified as high severity. The impact of this vulnerability is significant, as it can lead to unauthorized access and control over the affected application. Organizations using affected versions of Adobe Illustrator should prioritize remediation efforts.
The urgency for defenders is high, given the potential for exploitation. Users interacting with malicious files pose a clear risk, making it essential for organizations to implement immediate measures to mitigate the threat.
Organizations should prioritize patching immediately to safeguard against this vulnerability. Regular updates and user training can also help reduce the risk of exploitation.
Vulnerability Details
The vulnerability identified as CVE-2025-21133 is categorized under CWE-191. The affected product is Adobe Illustrator on iPad, specifically versions 3.0.7 and earlier. The vulnerability was publicly disclosed on January 14, 2025.
The CVSS vector for this vulnerability is CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating that it is locally exploitable, requires low attack complexity, does not require privileges, and necessitates user interaction. The impacts on confidentiality, integrity, and availability are all rated as high.
Technical Analysis
The root cause of this vulnerability is an integer underflow that can occur when processing specific files. Attackers may leverage this vulnerability by enticing users to open malicious files that trigger the underflow condition, leading to arbitrary code execution.
The attack vector is localized, meaning that an attacker must have access to the user's environment to exploit this vulnerability. The attack complexity is low, making it easier for an attacker to succeed. No special privileges are required, but user interaction is necessary for the exploit to work.
This vulnerability has high impacts on confidentiality, integrity, and availability, as an attacker could execute arbitrary code with the same privileges as the user running the application.
Risk & Impact Analysis
Risk to organizations includes significant potential data breaches and unauthorized access to sensitive information. The vulnerability can be exploited if users are tricked into opening malicious files, resulting in arbitrary code execution.
Given the widespread use of Adobe Illustrator on iPad, the blast radius of this vulnerability could affect many users and organizations, making quick remediation essential. Organizations should address this in their priority patch cycle to mitigate risks.
The urgency for action is amplified by the potential for exploitation through social engineering techniques. Organizations must ensure that their users are aware of the risks and trained to avoid opening suspicious files.
